using 5.12.256249.2599 and it won't update

It just crashes any time I try to update it. I don’t want to use version 6.x I tried it and didn’t like.

5.12.2599 Will not update as there are no updates, but if you are using the antivirus with it, it will update…

Using “Firewall” and “Defense+”… Not sure if that last bit is considered true AV or not. How can I manually update the AV component? The default manual update method appears to try to update something that can’t be updated. (firewall?)

Also, is it possible they’ve toned down all the advertising bundled with 6.x yet? I would love to use the latest version if it isn’t half as invasive as it was when I tried it awhile back.
